To all whom it may concern:

Be it known that I, WIRT B. BOYCE, a citizen of the United States,residing at the city of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in RollerShades, of which the following is a specification.

My invention relates to window shades in which the curtains'are mountedon spring rollers. The disadvantages of the ordinary arrangement inwhich one curtain is used to each window are well known. The window isprimarily shaded only at the end to which the shade roller is attached.And the window cannot be opened at the roller end without causing draftswhich quickly injure and destroy the curtain. It is de- .vide means bywhich a plurality of rollers may be mounted midway of the top and bottomof the casing, by which the window may be completely shaded if desired,both at the sides and at the point where the rollers are injuxtaposition, and by which the shades being movable toward the top andbottom of thewindow respectively,

' permit any'op'ening'of the sash either from the top or bottom asdesired, without-the currents of air passing therethrough and strikingthe curtains.

The principles of my invention. are illustrated in the drawings, inwhich- Figure 1 is an elevation of my improved window shading device,looked at'from the inside; Fig. 2 is asection of the same on the line2-2 of Fig. 1;

Fig. 3 is a detail perspective of a combi- ,nation bracket; and

Fig. 4 is a perspective of one end of my light shield. Furtherdescribing my invention with reference to the drawings, 1 represents thevertical sides; 2 the top, and 3- the sill of a window casing. Withinthe casing are two guillotine sashes, the upper one having .the rails 4and 5 and stiles 6 and 7, and the lower one having the rails 8 and 9 andthe stiles 10 and 11. At a point on the inside of the vertical portionsof the window casing opposite where the rails 5 and 8 overlap I mount aplurality of curtains on spring rollers. The upper curtain 12 is woundon the roller 13, and by means of cords 14: and 15, which'pass overrollers 14-. and. 15 and are connected to the single cord 16 may beadjusted at any desired height. =In like manner a lower roller 17 ismounted below the one last described',.and by means of a cord 18 may beadjusted as desired. The spring rollers should be mounted so as to take'up or unroll in opposite. directions, thereby placing the curtains onboth in practically the same vertical plane. There is necessarily acertain space left between the rollers to give free action even when thecurtains are wound on them. This space is increased as the curtains areunwound. To cover this space and make a complete curtaining of thewindow, when it is desired to shade the same, I provide a light shield,shown in Fig. 4. It may consist of a strip of shade cloth folded at 20,and having rows of stitching 21, spaced from each other so as to producean elongated loop from end to end, within which may be inserted astrengthening strip 22. The same should be placed in the rearof therollers so as to cover the variable space between them.

' While separate mountings may be provided for the rollers and for thelight shield, I prefer to assemble them in one bracket, as shown in Fig.3. This may consist of a plate 25, having a socket 26, adapted toprovide a bearing for the stub shaft at one end of an ordinary shaderoller, and a squared retainer 27 to take the squared or flattened endof the? spring shaft. It will be seen that the'brackets should be madein pairs, the bracket corresponding to the one shown being provided withthe shade.

retaining means in reversed relation. At a point centrally in the rearof the roller attachments should be placed a slotted receptacle 30 toreceive the ends of the strength ening strip 22. It will further benoted that the brackets constructed as shown provide means by which theseveral parts of the device, including the rollers and the light shieldtherefor, are placed in proper relative position to each other withoutspecial fitting or measurement when being installed.

Having thus fully described my invention what I claim and desire tosecure by Letters Patent is- I 1. In combination with a windowshademounting plate having a support thereon provided with parallelspaced walls, of a light shield consistin of a strip of fabriclongitudinally folds and having a plurality of rows of stitching spacedfrom each other and from the edges of said strip to form an elongatedloop from end to end of said strip, and a rectangular strengthening rodin said loop having the ends thereof projecting beyond the ends of saidstrip for reception in said supports whereby the light shield is held ina substantially rigid position.

2. A device of the class described com prising a mounting plate, aplurality of shade roller sockets carried thereby, a U-shaped supportcarried by saidplate, at a point between the shade roller supports andhaving spaced parallel walls and a light shield supported at its ends insaid U-shaped support and cooperating therewith to prevent relativerotary movement of the mounting plate and light shield.

In witness whereof, I have hereunto subscribed my name this 27th day ofOctober 1915, in the witnesses.
